VULCANIZER.

T 0 all whom it may concern:

Be it known that 1, Burns G. BoLnnr, a citizen of the United States, and resident of Oskaloosa, in the county of -Mahaska and State of Iowa, have invented a certain new and useful Vulcanizer, of which the following is a specification.

The object of my invention is to provide a small portable vulcanizer of simple,'durable and inexpensive construction.

A further object is to provide such a vulcanizer having a base, and which is provided also with a pivoted swinging arm carrying a pressure device designed to engage said base, the vulcanizer having means for pressing said arm toward said base;

Still a further object is to provide such a vulcanizer having a pressure device adapted to serve also as a fuel receptacle, and provided with a compartment for receiving a cooling liquid such as water, said pressure device being pivoted on said arm to permit it to be inverted from one position to another so that in one position it may be used with a liquid fuel, and in another position with a solid fuel or the like.

lVith these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a top or plan view of my improved vulcanizer.

Fig. 2 shows a side elevation of the same.

Fig. 3 shows a vertical, central, longitudinal, sectional view of the same, and

Fig. a shows a transverse, sectional, vertical, view taken on the line 44 of Fig. 1.

In the accompanying drawings, I have used the reference numeral 10 to indicate a base having a flat smooth upper surface, said base being provided with a handle device 11 extended away therefrom. Pivoted to the outer end of the handle 11 at 12 is a swinging arm 13 having at its forward end a yoke device, having the arms 14.

Pivotally mounted on the arms 14 is a pressure device, comprising a disk-shaped member 15, having one smooth flat surface and having on its opposite surface an annular peripheral flange or rim 16.

On the same surface of the pressure de- Specification of Letters Patent. PantQnted N 13, 1917. Application filed May 11, 1917.

vice is a second annular wall or flange 17 of greater depth than the flange 16, and preferably spaced inwardly from, and arranged concentric with the flange 16. I

The flange 17 is provided with extensions 18' which are pivoted to the ends of the arms spaced succession in a circle inwardly from the flange 17, length.

Mounted in the handle 11 is a screwthre'aded bolt 21 extending upwardly and through a suitableopening 22 in the arm 13.

On the upper end of the bolt 21 is a wing nut 23. Mounted on the bolt 21 between the arm 13 and the handle '11 is an expansible coil spring 21.

In the practical use of my improved vulcanizer, the tube to be vulcanized and the patch and other material are placed on the upper surface of the base 10. The smooth flat surface of the disk 15 is then placed upon the tube and the wing nut 23 is screwed on to the bolt 21 until the proper pressure is imposed on the tube.

lVater is poured into the channel formed between the flanges 16 and 17 and a prede termined amount of gasolene or other fuel is poured into the compartment within the wall 1'7.

The fuel is lighted and the vulcanizing completed in this manner.

If it is desired to use my improved vulcanizer with a solid fuel instead of with a liquid fuel, the pressure device is swung on its pivot points until it is inverted from the position-shown in Fig. 1 to the position shown in Fig. 3. The tube is placed on the base 10 in the manner already described, and a small cup is placed above the tube in such position that the ends of the posts 20 may be pressed downwardly into said cup, said cup being indicated by the reference character 25.

A solid fuel may then be used in the cup 25 for furnishing the proper heat for vulcanizing.

The advantages of my improved vulcanizer may be largely seen from the foregoing description.

I have provided a vulcanizer which. can

said posts being of equal be readily and easily, by slight adjustment of the pressure device, be used either with a liquid fuel or with a solid fuel.

I have also provided the pressure device having the fuel compartment in its top and the channel for water to serve as a cooling element to prevent the burning of the tube around the edge of the patch.

The entire device is of verysimple and inexpensive construction, and is compact in formand arranged so that it may be easily carried'in a tool box with an automobile.

Some changes may be made in the construction and arrangement of the parts of my improved vulcanizer without departing from the essential features and purposes of my invention, and it is my intention to cover by this application any such changes which maybe included within the scope of my claims.

I claim as my invention: n

1. In a device of the class described, a base, a pressure device having a smooth flat surface, and having on said opposite surface n annular flange, a second annular flange spaced inwardly from said first flange, whereby a channel is formed for receiving water or the like, and an inner compartment is formed for receiving fuel, said pressure device having on its last described surface upwardly extending posts, a pivoted arm, and means for pivotally mounting said pressure device on said arm for rotating it to different positions.

Copies of this patent may be obtained for five cent 2. In a device of the class described, a base, a pressure device having a smooth flat surface, and having on said opposite surface an annular flange, a second annular flange spaced inwardly from said first flange, whereby a channel is formed for receiving water or the like, and an inner compartment is formed for receiving fuel, said pressure device having on its last described surface upwardly extending posts, a pivoted arm, means for pivotally mounting said pressure device on said arm for rotating it to different positions, and means operatively connected with said arm for pressing said fuel device toward said post.

3. In a device of the class described, a base, a pressure device having a smooth flat surface, and having on said opposite surface an annular flange, a sec-0nd annular flange spaced inwardly from said first flange, whereby a channel is formed for receiving water or the like, and an inner compartment is formed for receiving fuel, said pressure device having on its last described surface upwardly extending posts, a pivoted arm, means for pivotally mounting said pressure device on said arm for rotating it to different positions, means operatively connected with said arm for pressing said fuel device toward said post, and a cup for receiving the upper ends of said posts.
